Significance values for analysis of covariance tests of the differences between high-impact and low-impact forests (e.g., reserves in high-impact vs. reserves in low-impact) shown in Fig. 2 (WFA) and Fig. 3 (sensor comparison).

aTests are: the decline of hot pixels with distance from roads (Distance), the difference between the numbers of hot pixels in low- and high-impact areas (Difference HI /LI) and the interaction between these two factors (Interaction Dist/Diff).bHot pixels are grouped into those inside (Res) and outside (Out) of reserves and are from the following data sets: World Fire Atlas (ATSR/AATSR sensors) 1996�C2006 (WFA), the World Fire Atlas (ATSR/AATSR sensors) 2001�C2003 (ATSR), and the Vegetation Fire Dynamics data set, including NOAA12 AVHRR 2001�C2003 (AVHRR) and MODIS Terra 2001�C2003 (MODIS). Values of one-tailed tests are marked with an asterisk (*) at a significance level of p
